This converts the following to Kconfig:
CONFIG_SPI
This partly involves updating code that assumes that CONFIG_SPI implies
things that are specific to the MPC8xx SPI driver. For now, just update
the CONFIG tests. This also involves reworking the default for
CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a
reasonable default, as it does not cause any compile failures.

While switching to readl_poll_timeout macros from custom code
the waiting condition was accidently inverted, so it was pure
luck that this code works at least in some conditions.
Fix that by inverting exit condition for readl_poll_timeout.

The QSPI controller on RCar Gen2 has 32byte FIFO. Instead of doing
the SPI transmission 1 byte at time, if there is a 32byte chunk of
data to be transferred, fill the FIFO completely and then transfer
the data to/from the FIFO. This increases the SPI NOR access speed
significantly.

Current DW SPI driver uses 32 bit access for some registers and
16 bit access for others. So if DW SPI IP is connected via bus
which doesn't support 16 bit access we will get bus error.
Fix that by switching to 32 bit access only instead of 16 and 32 bit mix
Additional Documentation to Support this Change:
The DW_apb_ssi databook states:
"All registers in the DW_apb_ssi are addressed at 32-bit boundaries
to remain consistent with the AHB bus. Where the physical size of
any register is less than 32-bits wide, the upper unused bits of
the 32-bit boundary are reserved. Writing to these bits has no
effect; reading from these bits returns 0." [1]

There is no sense in waiting for RX data in dw_reader function:
there is no chance that RX data will appear in RX FIFO if
RX FIFO is empty after previous TX write in dw_writer function.
So get rid of this waiting. After that we can get rid of dw_reader
return value and make it returning void. After that we can get rid
of dw_reader return value check in poll_transfer function.
With these changes we're getting closer to Linux DW SPI driver.

In current implementation we get -ETIMEDOUT error when we try to use
transmit only mode (SPI_TMOD_TO)
This happens because in transmit only mode input FIFO never gets any data
which breaks our logic in dw_reader(): we are waiting until RX data will be
ready in dw_reader, but this newer happens, so we return with error.
Fix that by using SPI_TMOD_TR instead of SPI_TMOD_TO which allows to use
RX FIFO.

0efc024 ("spi_flash: Add spi_flash_probe_fdt() to locate SPI by FDT
node") added a helper function spi_base_setup_slave_fdt to to set up a
SPI slave from a given FDT blob. The only user was the exynos SPI
driver.
But commit 73186c9 ("dm: exynos: Convert SPI to driver model") removed
the use of this function, hence rendering it obsolete.
Remove this function, as well as the CONFIG_OF_SPI option, which guarded
only this function.

This patch fixes a printf specifier style violation, reduces the scope
of a variable, and turns a void pointer that is used with pointer
arithmetic into a u8 pointer.

The QSPI module on i.MX7D is modified from i.MX6SX. The module used on
i.MX6UL/6ULL is reused from i.MX7D. They share same tx buffer size.
The endianness is not set at qspi driver initialization. So if we don't
boot from QSPI, we will get wrong endianness when accessing from AHB
address directly.
Add the compatible entry for 6ul/7d.

atcspi200 is Andestech spi ip which is embedded in
AE3XX and AE250 platforms. So rename as atcspi200
will be more reasonable to be used in different
platforms.
